Greg, We have multiple attachment points on the pedal as well as the z-bar on both ends to change for throw and leverage. I put the whole mounted clutch/flywheel unit in a press with a magnetic base dial indicator and measure how much movement at the TB/levers it takes to unlock the disc and how much to get any given disc air gap. Then you know exactly what the linkage needs to do and how the pedal stop should be adjusted. Shorten the pedal throw to quicken reaction and lengthen the throw to slow reaction.
